Hard disk space not getting listed for ESXi

Dear Experts:

Installed VMware ESXi5.0 on dell server, hard disks are configured with RAID5. ESXi is installed on pendrive and hard disk space availble is 1.2TB, from the vsphere client created data storage of 250GB and created VM and also installed guest OS now required to create few more datastore and use it for the VMs but hard disk is not getting listed when done the below steps:

Logged in to vspheres client did the following:
 Storage/Add Storage/Select Type/Disk/Lun when click on Next Disk space is not getting listed.

Please help how to make the remaining space of the server hard disk to be availble for the ESXi so that can create LUN's and use it for creating the VM's

Request you to also suggest me is this the recommended practice or please suggest me the best practice. Thanks in advance.

Yes. If you want to create multi (many) datastores for ESXi.

It's the RAID BIOS you need to Select.

when you created the first datastore, did you create it on the 1.2Tb space?

Sir, Thanks for the reply. I did not use the entire space used only 250GB out of 1.2TB. I was thinking can create multiple data stores with the availble total 1.2TB and create each VM under every data store. Please help.

What size is your array?

Normally when creating datastores, a datastore partition is created on the entire array.

Thanks sir. the entire array size is of 1.2TB this is listed while creating the first datastore but i selected custom and used only 250GB thinking can create the few more datastores later. Please suggest me shall i delete this and create the datastore on entire array.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
No you cannot, create multiple datastores on the same array.

Either carve up the Array into multiple LUNs (virtual disks or logical disks).

or Allocate Maximum Space to your datastore, which means, you will have to delete and start again.

Before deleting, you should be able to Increase the Space on that existing datastore.

Just select Properties of the datastore, and select Increase, and select the space unsusded space!

Sir, i read in book " It is best to create smaller virtual LUNs stripped across large physical LUNs" for this reason only i tried with 250GB datastore.

Sir, I have deleted the created datastore now total 1.2TB is free, please help me on the below points
1. creating the datastore for the entire array
2. how to create smaller virtual LUNs stripped across large physical LUNs

You create smaller Virtual LUNs, in the BIOS of the RAID Controller at startup, and not in ESXi.
